You need to try to contact Geo! When I did my 22 over I asked his advice, which lead me to move as much weight aft as possible. I now have a new tank just ahead of the engine and just about everything in the engine compartment is back as far as I could get it. The results have proven what he told me! The boat did 61 it had a Tempest 300 package with an Alpha, I build a very mild 383 it makes about 370 HP going from 300 to 370 with no CG change would have netted maybe 63. I also added a Bravo which steals about 3MPH over the Alpha! The boat on a good day runs 65.5, take close notice of go fast V hulls they sit very low in the stern. These hull need the CG aft, you have to realize our boats are built for the masses. They need to be commodious not strictly setup for speed, keep the weight aft and you will go faster. These hulls to get the nose up, only two ways to achieve this weight transfer aft or drive trim. Getting the nose up and keeping the drives thrust parallel to the water surface provides the best overall performance. Sure you can get great gains in speed with a lot ponies, but why not think about getting the CG in a better place. Don Tamm said it best you can overcome a lot with HP, I think you can achieve even more using you head.
